By what characteristics does Redis ensure high speed?

Answer from AI
- In-Memory Data Structure Store: Storing data in RAM provides minimal access latency.
- Single-threaded architecture: Simplifies locking and synchronization, reducing overhead.
- Non-blocking I/O: Using multiplexed I/O allows efficient handling of multiple concurrent requests.
- Optimized data structures: Implementation of efficient algorithms for primitive types, lists, hashes, sets, and sorted sets.
- Atomic Operations: Support for atomic operations ensures data integrity without the need for explicit client-side locks.
- Configurable persistence:
- RDB (Redis Database Backup): Snapshots of data at specified intervals.
- AOF (Append Only File): Logging all write operations for more precise recovery.
- Master-replication: Asynchronous data replication to replicas to enhance availability and read scalability.
- Sharding (Redis Cluster): Automatic distribution of data across multiple nodes for horizontal scaling.
